Check Digit Verification of cas no

The CAS Registry Mumber 233597-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,5,9 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 233597-40:
(8*2)+(7*3)+(6*3)+(5*5)+(4*9)+(3*7)+(2*4)+(1*0)=145
145 % 10 = 5
So 233597-40-5 is a valid CAS Registry Number.

7,7,8,8-Tetra(2-thienyl)-p-quinodimethanes. New electron-donating p-quinodimethanes

Kurata, Hiroyuki,Inase, Maki,Oda, Masaji

, p. 519 - 520 (1999)

Tetra(2-thienyl)-p-quinodimethanes, a new family of electronrich p-quinodimethane, show good amphoteric redox properties: in particular, the tetrakis(methylthio) derivative is an excellent electron-donor to form charge transfer complexes of good electrica
